What You Need To Know About Co-Signing A Mortgage

Danielle McIntosh • September 11, 2024

So you’re thinking about co-signing on a mortgage? Great, let’s talk about what that looks like. Although it’s nice to be in a position to help someone qualify for a mortgage, it’s not a decision that you should make lightly. Co-signing a mortgage could have a significant impact on your financial future. Here are some things to consider.


You’re fully responsible for the mortgage.


Regardless if you’re the principal borrower, co-borrower, or co-signor, if your name is on the mortgage, you are 100% responsible for the debt of the mortgage. Although the term co-signor makes it sound like you’re somehow removed from the actual mortgage, you have all the same legal obligations as everyone else on the mortgage. When you co-sign for a mortgage, you guarantee that the mortgage payments will be made, even if you aren’t the one making them.


So, if the primary applicant cannot make the payments for whatever reason, you’ll be expected to make them on their behalf. If payments aren’t made, and the mortgage goes into default, the lender will take legal action. This could negatively impact your credit score. So it’s an excellent idea to make sure you trust the primary applicant or have a way to monitor that payments are, in fact, being made so that you don’t end up in a bad financial situation.

 

You’re on the mortgage until they can qualify to remove you.


Once the initial mortgage term has been completed, you won’t be automatically removed from the mortgage. The primary applicant will have to make a new application in their own name and qualify for the mortgage on their own merit. If they don’t qualify, you’ll be kept on the mortgage for the next term.


So before co-signing, it’s a good idea to discuss how long you can expect your name will be on the mortgage. Having a clear and open conversation with the primary applicant and your independent mortgage professional will help outline expectations.


Co-signing a mortgage impacts your debt service ratio.


When you co-sign for a mortgage, all of the debt of the co-signed mortgage is counted in your debt service ratios. This means that if you’re looking to qualify for another mortgage in the future, you’ll have to include the payments of the co-signed mortgage in those calculations, even though you aren’t the one making the payments directly.


As this could significantly impact the amount you could borrow in the future, before you co-sign a mortgage, you’ll want to assess your financial future and decide if co-signing makes sense.


Co-signing a mortgage means helping someone get ahead.


While there are certainly things to consider when agreeing to co-sign on a mortgage application, chances are, by being a co-signor, you'll be helping someone you care for get ahead in life. The key to co-signing well is to outline expectations and over-communicate through the mortgage process.

Alternative Lending in Canada: What It Is and When It Makes Sense Not everyone fits into the traditional lending box—and that’s where alternative mortgage lenders come in. Alternative lending refers to any mortgage solution that falls outside of the typical big bank offerings. These lenders are flexible, creative, and focused on helping Canadians who may not qualify for traditional financing still access the real estate market. Let’s explore when alternative lending might be the right fit for you. 1. You Have Damaged Credit Bad credit doesn’t have to mean your homeownership dreams are over. Many alternative lenders take a big-picture approach . While credit scores matter, they’ll also look at: Stable employment Consistent income Size of your down payment or existing equity If your credit has taken a hit but you can demonstrate strong income and savings—or have a solid explanation for past credit issues— an alternative lender may approve your mortgage when a bank won’t. Pro tip: Use an alternative mortgage as a short-term solution while you rebuild your credit, then refinance into a traditional mortgage with better terms down the line. 2. You're Self-Employed Being your own boss has its perks—but mortgage approval isn’t usually one of them. Traditional lenders require verifiable, consistent income—often two years’ worth. But self-employed Canadians typically write off significant expenses, reducing their declared income. Alternative lenders are more flexible and understanding of self-employed income structures. If your business is profitable and your personal finances are healthy, you may qualify even with lower stated income. Even if interest rates are slightly higher, this option is often worth it—especially when balanced against tax planning and business deductions . 3. You Earn Non-Traditional Income Today’s income sources aren’t always conventional. If you earn through: Airbnb rentals Tips and gratuities Rideshare or delivery apps (like Uber or Uber Eats) Commissions or contracts You might face challenges with traditional lenders. Alternative lenders are often more willing to work with these non-standard income streams , especially if the rest of your mortgage application is strong. Some will consider a shorter income history or evaluate your average earnings in a more flexible way. 4. You Need Expanded Debt-Service Ratios Canada’s mortgage stress test has made it harder for many borrowers to qualify with big banks. Alternative lenders can offer more generous debt-service ratio limits —meaning you might be able to qualify for a larger mortgage or a more suitable home, especially in competitive markets. While traditional GDS/TDS limits typically sit at 35/42 or 39/44 (depending on your credit), some alternative lenders will go higher, especially if: You have a larger down payment Your loan-to-value ratio is lower Your overall financial profile is strong It’s not a free-for-all—but it’s more flexible than bank lending. So, Is Alternative Lending Right for You? Alternative lending is designed to offer solutions when life doesn’t fit the traditional mold . Whether you're rebuilding credit, running your own business, or earning income in new ways, this path could help you get into a home sooner—or keep your current one. And here’s the key: You can only access alternative lenders through the mortgage broker channel . Let’s Explore Your Options Not sure where you fit? That’s okay.
